To all whomit may concern:

Be it known thatI, FERDINAND BAUER, a citizen of the United States of America, residing at the city of St. Louis, in the State of Missouri, have invented certain new and .useful Improvements in Liquid-Coolimr A paratus, of which the following is a ful` c ear, and exact description, reference being had to the accom anying drawings, forming part of this speci cation.

My invention relates to that class of apparatus used for the `cooling of large quantities of liquids, such as water, by delivering them at the top of a shaft in which they descend in vertical sheets or films and in contact with ascending currents of air, whereby the heat in the water is extracted.

The object of the present im rovement is to provide a construction of t 's character whereby the air may be delivered horizontally into the cooling apparatus shaft at different elevations therein, Vthereby increasing the efiiciency of the apparatus as compared with similar apparatus 1n which air is forced upwardly directly through the shaft from the bottom to the top thereof.

A further object of my improvement is to provide more efficient vertically arranged istribution members for the liquid to be cooled in order that the air passed through the ap aratus will have better cooling effect upon tlJie liquid.

Figure I is a view partly in elevation and partly in vertical section of my ap aratus. Fig. II is a view partly in e1evat1on o the apn paratus viewed at a side at an an le to that in which it is viewed in Fig. I an partly in vertical section taken at right angles to the section shown in Fig. I. Fig. III Jis an enlarged vertical section of a portion of 'the interior structure of the ap aratus. Fig. IV is a vertical section taken tlirough art of the apparatus illustrated in Fig. III. V is a horizontal section taken on line V Fig. III. Fi VI is a horizontal section taken on lineVI- I,Fig. IV. Fig. VII is aview similar to I illustrating a modified construction of my ap aratus. Fig. VIII is a view similar to Fig. I illustrating the. modified oo nstruetion. Fig. IX is a view similar to Fig. III of the modified construction. Fig. X is a view similar to Fig.4 IV of the modified yconstruction. Fig. XI is a horizontal section taken on line XI-'XI, Fig. X.

In the accompanying rawings: 1 desigates a catch basin at the bottom of my apparatus into which the water that has been cooled is delivered.

2 is the casing of the apparatus within. which is a vertical shaft through which the liquid to be cooled descends 'vertically in sheets or films to be deposited in the catch basin. The shell 2 is' provided at one side with an air inlet 3 through which air is drawn' guard 7 that is inclined downwardly and toward the center of the shaft in the casing.

8 designates a receivin tank at the top of my a pai'atus into whic the liquid to be cooled) is delivered when conducted from a suitable source through the feed pipe 9.

10 are discharge pipes leading from the tank 8.

11 designates a series of overflow gutters located beneath the discharge pipes 10 and into which the liquid to be cooled is emptied by said pipes. These gutters preferably have serrated side walls, as seen most clearly in Fig. IV. The utters 11 are arranged in series parallel wit each other and extend across the interior of the casing 2 or the shaft of my apparatus andbeneath each utter is a vertical web 12 on which the liquid to be cooled descends as it overflows from the gutter, thereb exposing a thin sheet or film of liquid to t e cooling action of air delivered laterally into the shaft of the apparatus. The vertical webs 12 are held in a separated condition by distance ieces 13 mounted upon rails 14, see Figs. IIEI) and IV, that serve as su ports for said distance ieces and also for t e overliow gutters'an their vertical webs. Y

15 are vertical liquid distributing members extendin ,uninterruptedlyV across the space within t e casing 2 and .vertically positioned in series beneath and in alinement with the overflow utters '11 and their vertical webs, there eing preferably several tiers of these distributing members and the number of members in-each tier being in correspondence to the number of overflow gutters at the top of the apparatus. Each distributin member is provided at its upper end wit a trough 16 into which the liquid descends to overfiow therefrom and descend upon the vertical web of the member in a thin sheet or film in correspondence to its flow at the exterior of the gutters 11 and the vertical webs beneath said gutters. The liquid is delivered from the vertical webs of the overllow-guttels into the troughs of the upper tier of the vertical liquid distributing members 15 and thereafter falls from each set of the vertical liquid distributing memupon the liquid by the contact of the air that is delivered laterallyr into the shaft of the aparatus. The various tiers or sets of vertical liquid distributing members 15 are supported by side rails 14 beneath the side rails that sup ort the overflow gutters 11 and said vertica liquid distributing members are maintained in their proper positions by distance members 17 located between the vertical liquid distributing members 15 and above the side rails by which said vertical liquid distributing members are supported.

The overflow gutters 11 and their vertical webs 12 and the vertical liquid distributing members 15 and their troughs 16 are in the construction illustrated in Figs. I to VI inclusive, made of metal, this material being preferably employed by reason of the fact that better cooling action for the liquid may be thereby secured and the durability of the parts mentioned is greater than it would be if such parts were made of wood.

The air for cooling eect upon the liquid to be cooled in my ap aratus is forced into the duct 5 as previous y explained and this air asses laterally from said duct into the shaft of the apparatus between the vertical liquid distributing members 15 at different levels in the shaft; The delivery of the air at such different levels is accom lished by means of flues to be next describe A designates the air delivery flues horizontally positioned in the apparatus and which consist of perforated vertical side plates 18 that are held separated from each other by parting strips 19. The flues A are open at their ends which are presented to the duct 5 and the wall of the casing against which said ends of the flues abut are perforated in order that the air forced into said duct may be delivered laterally into the flues A to be distributed within the shaft of the apparatus according to the location of any particular flue-whether at one level in the .apparatus or a higher or lower level in the a paratus. By providing the air distributing ues A at the different levels I deliver the air laterally from the duct 5 into said ilues irrespective of the other flues above or beneath any particular flue so that theair discharged laterally therefrom will have a more efiicient cooling effect on the liquid passing, through the apparatus than it would if the flues were all located in a common level or'if the air was delivered entirely at the bottom of the apparatus and forced upwardly through the shaft.

In Figs. VII to XI inclusive7 I have shown a modified construction of my apparatus.. The construction in this modification corresponds in general to the construction previ-- ously described and the only characteristic features of distinction between the construction in the modification and the previously described construction are to be found in the construction of the vertical liquid distributing lmembers in the apparatus. These vertical liquid distributing members comprise the overflow gutters 11 mounted in the vertically disposed wooden slats 12 that take the place of the Vertical webs 12 between the overflow gutters 11 and they also comprise the vertical liqui'd distributing members 15 in the shape of vertically `disposed wooden slats that are provided at their top edges with troughs 16 into which the liquid descends to overiiow therefrom onto the vertical distributing members 15 and descendthroughout the apparatus onto the succeeding vertical liquid distributing members. The horizontal air distributing flues A are located between the vertical liquid distributing members 15 in corres ondence to their locations in the previous y described construction and the liquid to be cooled and the air for cooling effect upon the liquid are delivered into the apparatus in essentially thesame manner vas that previously described.

I claim:

1. A liquid cooling apparatus comprising a easin provided with an air duct, vertical liquid lstributing members in said casing, air distributing means in said casing by which air is conducted from said duct in a direction transverse of said casing, 'and means for forcing air into said duct and therefrom rated flues horizontally disposed within said casing between said vertical, liquid distributing members and having communication With said duct, and means for forcing air through said ductand into said lues, substantially es set forth.
